How many battery storage projects commenced construction in 2025?
In addition to the six projects that reached financial commitment, a further three battery storage projects commenced construction in the first quarter of 2025, with a total of 840 MW / 2.9 GWh in storage capacity / energy output.
Why should Australia invest in energy storage systems?
Energy storage systems, such as big batteries, are a critical part of Australia’s future energy mix and act as a reliable back-up system allowing us to store renewable energy for when it is needed most and keep the lights on under all conditions. It’s great to see the high levels of investment we’ve seen over the past couple of years continue.
Are battery energy storage system capital costs improving in 2024-25?
Image: Fluence. A new report published by Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) has found that large-scale battery energy storage system (BESS) capital costs have improved the most in 2024-25, falling by 20% year-on-year (YoY).
Why is battery storage important in Australia?
Battery storage is now key to Australia’s clean energy transition. It stabilizes supply by storing extra renewable energy and delivering it on demand, even when solar or wind output drops. This helps prevent blackouts and ensures steady green energy flow. BESS installations are expected to double by 2027.
How has Bess impacted Australia's electricity market?
BESS stood out with an 85% increase in investment year-over-year. These systems store solar and wind power, releasing it when demand peaks. This growth raised BESS output in the National Electricity Market by 86%, according to the Australian Energy Market Operator (AEMO).
Why is capital expenditure important when building a battery energy storage system?
This has led to multiple gigawatts of grid-scale battery energy storage systems in various stages of development in Australia. Each of them requires significant investment, with millions of dollars at stake and years-long development timelines. As a result, capital expenditure, or capex, is an important consideration when building a battery.
